AES-256 A byte-oriented portable AES-256 implementation in C. Solaris Cryptographic Framework offers multiple implementations, with kernel providers for hardware acceleration on x86 (using the Intel AES instruction set) and on SPARC (using the SPARC AES instruction set). It is available in Solaris and derivatives, as of Solaris 10.
The implementation of AES in products intended to protect national security systems and/or information must be reviewed and certified by NSA prior to their acquisition and use. AES has 10 rounds for 128-bit keys, 12 rounds for 192-bit keys, and 14 rounds for 256-bit keys.
Advanced Encryption Standard process. The Advanced Encryption Standard (AES), the symmetric block cipher ratified as a standard by National Institute of Standards and Technology of the United States (NIST), was chosen using a process lasting from 1997 to 2000 that was markedly more open and transparent than its predecessor, the Data Encryption ...
AES-NI (or the Intel Advanced Encryption Standard New Instructions; AES-NI) was the first major implementation. AES-NI is an extension to the x86 instruction set architecture for microprocessors from Intel and AMD proposed by Intel in March 2008. A wider version of AES-NI, AVX-512 Vector AES instructions (VAES), is found in AVX-512.
Authenticated Encryption (AE) is an encryption scheme which simultaneously assures the data confidentiality (also known as privacy: the encrypted message is impossible to understand without the knowledge of a secret key [1]) and authenticity (in other words, it is unforgeable: [2] the encrypted message includes an authentication tag that the ...
The Rijndael S-box was specifically designed to be resistant to linear and differential cryptanalysis. This was done by minimizing the correlation between linear transformations of input/output bits, and at the same time minimizing the difference propagation probability. The Rijndael S-box can be replaced in the Rijndael cipher, [1] which ...
The Key Wrap algorithms are intended for applications such as protecting keys while in untrusted storage or transmitting keys over untrusted communications networks. The constructions are typically built from standard primitives such as block ciphers and cryptographic hash functions . Key Wrap may be considered as a form of key encapsulation ...
Rijndael MixColumns. The MixColumns operation performed by the Rijndael cipher or Advanced Encryption Standard is, along with the ShiftRows step, its primary source of diffusion . Each column of bytes is treated as a four-term polynomial , each byte representing an element in the Galois field . The coefficients are elements within the prime sub ...
